556 HP HUMMER GT ROCKETS TO 140 MPH
Published: Oct 20, 2006
The Hummer GT is a 556 horsepower Supertruck that can rocket to 140 mph. It includes stuff you must need like gullwing doors and I'm sure it doesn't use very much gas at all. ;) Giz Magazine explains: "The six-litre engine is upgraded by the GeigerCars.de engine experts using a supercharger kit and a stainless steel high performance exhaust system including special manifolds and a specially calibrated ECU. The modifications increase the peak power to 556 hp / 409 kW while the maximum torque is increased to 765 Nm. The road performances are excellent: The tuned SUV only takes 7.9 seconds from 0 â€“ 100 km/h. Maximum speed is about 225 km/h."
